Question

What is the solution for the equation 8X – 12 = 4x?
x= 48
x= 30
x=3
X=1

Answer 1

8x-12= 4x

move -12 to the other side

sign changes from -12 to +12

8x-12+12= 4x+12

8x=4x+12

move 4x to the other side.

sign changes from +4x to -4x

8x-4x= 4x-4x+12

8x-4x= 12

4x=12

divide both sides by 4 to get x by itself

4x/4= 12/4

Answer: x= 3

C. x = 3

Explanation:

8x - 12 = 4x
